My new K702s just showed up. And, like, what the heck? They.... have absolutely no bass and sound very sharp and overly tipped to the highs. This is coming from my K240 Sextett MP, which I never regarded as a particularly bass heavy headphone in the first place...

But this...??

I am not really a believer in burn in. Is this what everybody experiences at first?

Any suggestions?

I don't remember what the K701 sounds like, since I only listened for a few minutes at a meet, but I thought the MP Sextett had too much bass which was bloated, and not enough and poorly extended treble. It might just be preferences or maybe something psychological due to a different presentation of sound.

They need a LOT of burn in, believe it or not, and why it's so hard to admit that mechanical parts need break in period.

K701 took ages to burn in. Literally hundreds of hours. And they improved all the time. Still although somewhat flat out of the box I wouldn't say they had no bass at all...

From my experience, after 100-120 burn in. The turbo bass kick in, let's see if it's gonna change your belief system...

Tip, Try the burn in process with electronic music. full bass and a large sound spectrum. help to open the drivers all over the 3D...

well, the k701s that i own definately was bass shy and a little silbilant and grainy at the top out of the box.

After about 400+ hours they have definately transformed into a VERY clean headphone with no grain or sibilance whatsoever.

As for bass performance, i never felt that the k701 had much slam to its bass. It definately has good tonality and goes quite deep after a good 300-400 hours.

I would definately keep them for much longer to see if they develop to your liking. After that if the bass doesnt do it for you, then you probably should look for a different phone. The treble however becomes very clean after burn in so no worries there.

hope that helps

What's your source? You are going to need a very warm source to get a decent amount of bass from them. But at the end of the day don't expect too much bass from them, the K701 is legendary for being bass anemic.

I found the K-701 to be dependent on the amp. Very picky, as AKG headphones tend to be. I had 30-40 hours on mine but had a night and day difference when plugging them into a good amp.

they were even more bass light than k501 and sounded like turd so i'm not surprised you got the 'What' reaction...

the akg 701 will make you a big believer in burn in. mine took several hundred hours of burn in to sound right. I just plugged them in to music and stuck them in a drawer for a couple weeks checking on them peiodically. its really kinda fun to hear the sound changes that happen after a week or two.

I will burn them in only because it's free (well, relatively speaking). I don't expect much from this, but I don't want my purchase to be in vein either.

They no longer sound as horrible as they did out of the box, but only because I have become accustomed to the sound and there are probably psychologic factors at work as well, due to me wanting them to sound good.

I don't remember burning in adding any bass to mine though.

Whatever you need to tell yourself

It's funny how burn-in, which is apparently a mechanical process, magically makes bass stronger for lean headphones and makes bass leaner for bassy headphones.

The former is supposedly explained by the diaphragm becoming more flexible. But, in the latter case, taking into account the same effect, bass would become even more pronounced.

Like I said, it's free, so no harm in covering all bases.
